2. the perimeter of a rectangular flower garden is 80 m and its area is 375 m2. find the length of the garden.

The perimeter of a rectangular flower garden is 80 m and its area is 375 m^2.

Perimeter of rectangular flower garden = 80 m

Now we know the formula for perimeter of rectangular flower garden = 2(l+w)

, where l and w are the length and width of the rectangular garden respectively

So it means

2(l+w) = 80

Divide both sides by 2

l+w = 40

We get 1 equation .

Now lets use area

Area = 375 square meters

We know the formula for area

Area = length * width = lw

It means

lw = 375

We get 2nd equation

We can write it as w= 375/l , and use it in first equation

we get

l + 375/l = 40

Multiply whole equation by l

we get

or

we can factor it now

so we get

(l-15)(l-25) =0

l-15 =0 or l-25 = 0

So we get l=15 or l=25

But length should be higher

So length = 25 m
